Guidance required on tuning quad


#1

Ok, so I’ve built my first quad (Hurray) and it flew first time with no problems (WOW) I thought I’d use the same stack as my EMAX Hawk 5 as the Emax Magnum stack is just brilliant in the Hawk 5. So the build is as follows:

Tinsly S50 Big Shark Frame - https://www.banggood.com/Tinsly-S50-Big-Shark-215mm-5-Inch-FPV-Racing-Frame-4mm-Arm-Thickness-w-5V-12V-PDB-for-RC-Drone-p-1231513.html
Emax Magnum All in one stack - https://www.unmannedtechshop.co.uk/emax-f4-magnum-v2-all-in-one-fpv-stack-tower-system/
Mr Copper 2306 2700KV Motors - https://www.unmannedtechshop.co.uk/mr-copper-2306-2700kv-brushless-motor/
Diatone 5045 Props - https://www.unmannedtechshop.co.uk/diatone-5045-v2-tri-blade-propeller-pack-of-4/
FPV Camera - Runcam Eagle 2 Pro (Very very nice image!)

So all good on paper. In flight though it’s a different matter. I seem to have built a quadcopter that would be amazing for beginners. Note this is when comparing it with Hawk 5.

Throttle response is very sluggish with barely any punch out.
Top speed - feels like 10mph!

Upshot - I’m wondering - is it the configuration, or is it the electronics?
Any guidance points or hints on where I should start looking to improve performance what be gratefully recieved.

If you are using a 4s battery, my guess would be that your Quad is not using 100% of the possible Throttle Range.
Try to recalibrated your Escs and check your Throttle settings in Betaflight and your Taranis.

Thanks Luca - it is a 4S 100C battery. I’ve also added a capacitor to the battery wiring as well.
Only other difference is that I’m running Betaflight 4.5.1 on the Tinsly and 4.3.1 on the Hawk 5.

Follow @Luca advice…
Calibrate ESCs
Check transmitter throttle stick is giving full range either -1000 : 0 : 1000 or 1000 : 1500 : 2000 depending how it is shown on your TX
